American theoretical physicist, considered the founder of quantum optics. He developed the theory of higher-order optical coherence, introduced the concept of coherent states (Glauber states), and explained photon statistics in laser radiation. Winner of the Nobel Prize in 2005.

Biography

Born in New York. He received his PhD from Harvard. At age 18, he participated in the Manhattan Project. He worked at the Institute for Advanced Study, Caltech, and Harvard University. The Nobel Prize was awarded for his contribution to the quantum theory of optical coherence.

Key discoveries

💡 As a student, he was recruited for the Manhattan Project, where at age 18 he calculated nuclear reaction cross sections for the atomic bomb.
